Abstract: 272,663. Schlotterhose, C. May 17, 1926. Right to Patent relinquished. Sterilizing fish materials. -In making fish meal the raw materials are first sterilized by indirectly heating by steam to a temperature of not over 105‹ C., without admitting moisture or heated air, and are then dried and worked up to meal. In the process described, the raw material is first disintegrated in a machine 1 by two oppositely rotating rollers carrying steel blades, and is next raised by a worm conveyer 2 to the sterilizer 3, which consists of a drum with a mixing and conveying device and a steam heating jacket. Gases and vapours arising in the sterilization are withdrawn through tubes 4 ,5, by an exhauster 7. The material next passes to a drier consisting of four drums 4a - - 4d heated up to 60‹ C. by a steam jacket and having stirring and conveying blades mounted on rotating shafts. Heated air is conducted through the drums in the direction opposite to that of the material. The gases from the drying are exhausted through branches tubes 6<a> - - 6<d> and main tube 5 and pass, with the gases &c. from the sterilizer 3, through water scrubbing towers 8 to remove evil-smelling constituents, the unabsorbed gases being passed through a water trap 10 to a furnace 11 where they are completely burned. The water of condensation is withdrawn through traps &c. from the sterilizing and drying drums. The dried material is caried by a worm 12 and elevator 13, in which it is partly cooled, to a disintegrator 15 formed with exchangeable toothed cheeks co-operating with rapidly rotated beating drums. The meal produced is raised by an elevaor 17 to a sifter 18 consisting of a rotating cylinder covered with wire gauze and having beating arms rotating in the opposite direction. The meal passes to a box 18<a> from which it is filled into bags. The residue from sifter 18 is returned to the disintegrator. The Specification also refers to processes for the production of fish meal in which steam at pressures up to 4 atmospheres and at temperatures up to 155‹ C. is employed ; in which a, rotary vacuum vessel heated by passing steam at 130‹ C. through a jacket thereon is used; in which the materials are converted into a pulp with hot water or steam and the water then removed by pressure or heated rollers; and in which the noxious gases and vapours produced in the process are removed by filtration through peat dust or lime, or by adding ozone, chlorine, or other suitable gas. A process for sterilizing raw meat by passage through a drum having a heating jacket is also referred to.
